Choppy TV Image

I have an entertainment/gaming system that I've upgraded and or replaced every hardware component except the HDD. Problem that's become worse over time is the tv picture starts to become choppy after a few minutes of use, until the image freezes altogether. When I first built the system, I would only get occasional choppy images. Now, the problem is continuos. I have changed tv cards from one 550 pro to another. I have added an ATI HDTV tuner with the same results. I have upgraded all drivers and even upgraded the PSU, cpu, graphics card, ram and motherboard. I don't think it's heat related since the problem happens in winter or summer with or without the cover on. Also, the image gets choppy regardless of whether I use Cyberlink, MCE 2005 or ATI Multimedia. I have also tried a different monitor and tried dvi and vga.

The only thing I have noticed is that this only occurs on live tv. Recorded tv (from a while back before this problem became so pronounced) plays back fine. The last thing I can guess is strength of the cable signal, which I'm awaiting a Motorola signal booster.

Other then that, I'm out of ideas. Any suggestions?
